Hi Bob,
That's the one, and from what you have said they are still using it. They are more than a little proud of this arrangement. I have to admit that it makes some sense, but I am not really sure how it performs. I've never looked at it from a perspective of distortion or quality.

I did hear that the newer units no longer have that quirky bias problem. Nice to hear.

Joshua, if you ever come to visit me, it might be fun to test line cords.
I have an almost perfect set-up with a STAX Lambda Pro headphone system with vacuum tube direct drive. It is VERY sensitive to line cords, AND even Bybees. I have one of Bob Crump's super silver line cords on the unit now, that might make a good reference.
I listen first, also, before I condemn.

You would be so cheap as to revert to the original AMPZILLA in input stage implementation. Then we could avoid fets, matching, AND we could ADD some electrolytic caps. :devily:

You can do a lot worse for a lot more money than the Ampzilla. Properly cleaned up it sounds like music to me; add FETs for the differentials and, well you'd just have to build one and listen to it.

Is this a joke or are you seriously meaning this nonsense?

I mean it. It is hard to reproduce acoustic of a real temple with both organ and violin playing. First of all, it is hard to record properly so instruments and reverberation recorded sounding from a stereo system will create an imagination of presence in the environment. Second, instruments themselves are very rich. Third, a duet of musicians is superb. And they selected exceptional material of best composers to play and record. As the result, I have one disk to test my reproduction systems I design including amps, speakers, room acoustic, enjoying the music at the same time. I wish I would have another one such a CD...
